When the outbreak of Covid-19 forced individuals to retreat to their homes in early 2020, computer scientist Tom Zahavy rediscovers his passion for chess. Despite not being a top player, Zahavy delves into chess puzzles, which present intricate scenarios challenging players to think creatively.
These puzzles not only aid in honing players’ skills but also shed light on the limitations of chess programs. For instance, a puzzle crafted by mathematician Sir Roger Penrose exposes the difficulty computers face in handling unconventional scenarios where the odds seem stacked against them. This disparity underscores the fact that while computers excel in defeating human players, they still struggle with certain complex problems.
Zahavy, intrigued by Penrose’s puzzles, delves deeper into the realm of creative problem-solving. As a research scientist at Google DeepMind, he embarks on a journey to develop AI systems capable of exhibiting a range of behaviors beyond mere task completion.
In a groundbreaking move, Zahavy and his team merge the strategies of multiple AI systems, including the formidable AlphaZero, to enhance chess gameplay. This collaborative approach not only outperforms AlphaZero but also demonstrates superior problem-solving skills, especially when faced with challenging puzzles like those posed by Penrose.
The concept of amalgamating diverse AI systems to tackle intricate problems extends far beyond the chessboard. This innovative method of problem-solving mirrors human brainstorming sessions, leading to creative and effective solutions that might otherwise remain undiscovered.
Zahavy’s pioneering work underscores the importance of embracing diversity in AI systems to navigate complex challenges successfully. By fostering a collaborative environment among AI agents, researchers can unlock a myriad of solutions, paving the way for enhanced performance across various domains beyond chess.
Through Zahavy’s research, the narrative of AI development shifts towards a more inclusive and diversified approach, mirroring the collaborative spirit that often drives breakthrough innovations in diverse fields.
